Clean filters - Here is how I do!

[Corpze]

Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism.
How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess...

Anyway, here is the video

Brush off the rough muck with a camel hair brush and then clean them in a sink of luke-warm water with a few drops of washing up liquid and my fingers.  Final rinse in RO water and dry them off with a fresh 100% cotton wool ball (for each touch on the surface = new cotton wool ball).  There is no rocket science involved.

Filling a bathroom full of steam, then taking your optics in to clean / assemble is a great way of keeping dust out, just be sure all of the moisture in the air has cleared first.

It’s probably the closest you’ll get to a cleanroom at home.

I thought it was just me that did this...I have a wet room so no mats and I remove all the towels too and even wear one of the "clean room" all in ones with a plastic hat for good measure.

Yep that would be very effective!

Tyvek suits are perfect for this, they have fitted hoods.

I might get one of these suits and have one at hand next time i clean my filter, usually once a year after the dark season has ended here in Sweden.
I have a guest bathroom which is "empty" so to speak...

Great advise!

Now that we all have face masks its worth wearing one when cleaning optics, its amazing how much moisture/droplets comes from your mouth and nose ..

Eyelashes are something else you might not notice falling into the job too!
